Detailed Description

The QRadioData class provides interfaces to the RDS functionality of the system radio. The radio data object will emit signals for any changes in radio data. You can enable or disable alternative frequency with using the setAlternativeFrequenciesEnabled() method.

To obtain QRadioData instance retrieve the QRadioTuner::radioData property.

radio = new QRadioTuner;

radioData = radio->radioData();

Alternatively, you can pass an instance of QRadioTuner to the constructor to QRadioData.

Constructor & Destructor Documentation

QRadioData::QRadioData	(	QMediaObject *	mediaObject,
		QObject *	parent = `nullptr`
	)

explicit

Constructs a radio data based on a mediaObject and parent.

The mediaObject should be an instance of QRadioTuner. It is preferable to use the QRadioTuner::radioData() property on a QRadioTuner instance to get an instance of QRadioData.

During construction this class is bound to the mediaObject using the QMediaObject::bind() method.

QRadioData::~QRadioData ( )

Destroys a radio data.

Method Documentation

void QRadioData::alternativeFrequenciesEnabledChanged ( bool enabled )

signal

Signals that automatically tuning to alternative frequencies has been enabled or disabled according to enabled.

QMultimedia::AvailabilityStatus QRadioData::availability ( ) const

Returns the availability of the radio data service.

A long as there is a media service which provides radio functionality, then the QMultimedia::AvailabilityStatus will be that of the QRadioTuner::availability().

QRadioData::Error QRadioData::error ( ) const

Returns the error state of a radio data.

See also: errorString()

void QRadioData::error ( QRadioData::Error error )

signal

Signals that an error occurred.

QString QRadioData::errorString ( ) const

Returns a description of a radio data's error state.

See also: error()

bool QRadioData::isAlternativeFrequenciesEnabled ( ) const

Documentation pending.

QMediaObject* QRadioData::mediaObject ( ) const

overridevirtual

Return the currently attached media object.

Implements QMediaBindableInterface::mediaObject()

QRadioData::ProgramType QRadioData::programType ( ) const

QString QRadioData::stationId ( ) const

Documentation pending.

void QRadioData::stationIdChanged ( QString stationId )

signal

Signals that the Program Identification code has changed to stationId.

QString QRadioData::stationName ( ) const
